## Experience

### Indie Hacker (current)

October 2024 - Present

Turning ideas into products across Solana, AI, and the full stack—20+ experiments, several live. Building Pawket, a Solana-powered companion game; Khaata, a non-custodial USDC merchant POS; and Praxis, a conversational Solana agent with on-chain spending limits. I handle the whole loop: architecture, code, tests, deployment, and iteration. React/Next.js, Node, Postgres, Redis workers, Rust/Anchor, wallet integrations, and LLM tool-calling.

### Superteam Member (current)

July 2026 - Present

Joined the Superteam ecosystem through the Solana Fellowship. Built Praxis with Rust and Anchor, and published @usepraxis/sdk as a typed Node client. Backed the system with 20+ automated server-side test suites, bringing a testing-first mindset to on-chain product development.

### Odoo S.A.

April 2023 - September 2024

Delivered 30+ fixes and features across HR, payroll, timesheets, Documents, Field Service, and Planning in Odoo's production Python codebase. Worked across release cycles with a focus on correctness, backward compatibility, and dependable upgrades. Experience shipping inside a mature business platform—not just starting projects from scratch.
